摘　　要：选择完成系列产前检查并有分娩记录的 6 35例正常孕妇为观察对象 ,记录其 2 8孕周时的胎位为初诊胎位 ,此后分别于孕 32周、36周检查记录胎位 ,并与分娩前胎位对照。结果显示 ,整个晚期妊娠中胎位都在不停地变化 ,到妊娠 36周以后 ,多数转为头位。提示在第 2 8孕周时即应注意对异常胎位的纠正 ,横位可能是臀位转为头位的过程 ,并且较臀位更易于转变为头位 ;初产妇的胎位在第 32孕周后多已固定 ,而经产妇的胎位固定多在第 36孕周以后。初产妇胎位纠正应力争在 32孕周以前完成 ;而经产妇在 36孕周发现异常胎位时也应积极纠正 ,以促其向头位转变。cases of gravid women who received antepartum care and delivered were studied The fetal position was recorded at the 28th pregnant week(PW)and the similar work was performed at the 32th PW,36th PW respectively,and they were compared with the positions at parturition The results showed that the fetal positions vary continually during the third trimester pregnancy Most fetuses were being cephalic presentation after 36th PW and maintaining to childbirth The rectification of abnormal fetal position should be carried through from the 28th PW Transverse presentation is perhaps a duration from breech presentation to cephalic presentation and possibly is much easier to translated into cephalic presentation The fetal position is formed at the 32nd PW in first gravid women and the abnormal position of fetus should be recreated at/before the days as possible The same occur at the 36th PW in multiparous,so great efforts translating their abnormal fetal position into cephalic presentation should be made at/after that
